About

Antichamber is a game about discovery, set inside a vibrant, minimalistic, Escher-like world, where geometry and space follow unfamiliar rules, and many obstacles are a matter of perception.

Journey through the depths within a non-Euclidean labyrinth, as you create, destroy and manipulate matter, and uncover new ways to overcome your surroundings in this mind-bending psychological exploration game.

Startup Crash Fixes/Solutions

For anyone experiencing startup crashes, here are all the available "fixes/solutions" that the community on the Antichamber subreddit and the Antichamber wiki have been able to come up with thus far:

Run the game as an Administrator

Browse to "%installdir%\Antichamber\Binaries\Win32\"

Right-click UDK.exe and go to Properties

Go to the compatibility tab and check the box for "Run this program as an administrator" (Maybe also enable compatibility mode for Windows 7)
